Abstract

The invention discloses a precast concrete slab column node and a connecting method thereof, and relates to the field of civil engineering. The precast concrete slab column node solves the problems of poor economic performance, low construction speed, casting difficulty and complicated steel bar structures in the existing slab column node region. The slab column node comprises a precast concrete column, a precast concrete slab, four pieces of lower end support angle steel and four pieces of upper end fixing angle steel, wherein a rectangular through hole is formed in the middle part of the precast concrete slab; the precast concrete column is inserted and arranged in the rectangular through hole; one piece of lower end support angle steel and one piece of upper end fixing angle steel are arranged on the side wall of the precast concrete column; one end of each piece of lower end support angle steel and one end of each piece of upper end fixing angle steel are fixedly connected onto the side wall of the precast concrete column; the other end of each piece of lower end support angle steel is fixedly connected onto the lower end surface of the precast concrete slab; the other end of each piece of upper end fixing angle steel is fixedly connected onto the upper end surface of the precast concrete slab. The connecting method comprises the steps of positioning installation; precast concrete slab positioning; precast concrete slab fixation. The precast concrete slab column node and the connecting method are used for forming a precast slab column structure.

Description

technical field [0001] The invention relates to a prefabricated concrete slab-column joint and a connection method thereof. Background technique [0002] The space of the slab-column structure is unobstructed and concise, and the plane layout is flexible, which realizes no beams in the room, and is suitable for multi-high-rise civil buildings and industrial buildings such as factories and warehouses. At present, in the cast-in-place concrete slab-column structure, the joint area where the slab and column intersect should have sufficient bending, shear and punching resistance. The steel reinforcement structure in the joint area is complex and densely arranged, which often makes concrete pouring difficult. It is not conducive to ensuring the quality of structural concrete, and the construction speed is slow; a large number of formwork and supports are required in the construction process of cast-in-place concrete slab-column structures, and the reuse rate is low, resulting in ...
